Facebook and Google have a problem I am familiar with: Not Invented Yet Syndrome. Typically they face a problem that few people have ever faced. There may be an existing solution, but not in the open. So they have to roll their own. Others in this thread say Buck was inspired by Blaze. That seems reasonable and I hardly think Facebook can be blamed for rolling their own when that was the only available option. You might as well blame Google for fragmenting the Hadoop ecosystem by creating their MapReduce framework.
